My horns are not the ones that are used on the 3678 if that is what you mean?
As I said, I have level matched the HF and LF sections by setting them according to their sensitivity. I have verified this with REW, so no reason to turn down the HF :)
Dont underestimate the size of the horns...:

Almost same size as a 32" TV.
I know that the space between them is not optimal, but my room is not big enough for more space. My next place, I will have a dedicated room for the home theater (currently its both living room and home theater), and hopefully it will be big enough to space out the speakers a little more. I'm getting good seperation of the sounds though. I can easily pinpoint the sound to the screen when the sounds travels from one speaker to the other. (The Pixar intro is a very good example!).
